WHIFFLETREE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 245,419, dated. August9, 1881,

Application filed December 15, 1880.

. To all whom it may concern:

Beit known that we, FRANK S. VVAGEN- HALS and CHAUNOEY 1. KING, ofColumbus, in the county of Franklin and State of Ohio, have invented anew and Improved Whitfietree Attachment; and we do hereby declare thatthe following is a full, clear, and exact description of the same.

Our invention is an improved spring attachment for double-trees orwhiffletrees for the purpose of relieving the shoulders of thedraftanimals of jars or shocks. The attachment is applied to adouble-tree or whilfletree, as shown in accompanying drawings, in which-Figure 1 is a sectional view, and Fig. 2 an outside view, a portion ofthe clevis being broken away. Fig. 3 is a plan view of the metalguard-plate attached to the double-tree.

The main parts of the attachment are the U-shaped clevis or draft-loopA, the box B, pivoted to the rear side of the double-tree, the spring 0,contained in box, and the plates D, E, and F,applied,respectively, tothefront and rear sides of the double-tree and to the open rear end ofsaid box, as shown. The legs aof the clevis A embrace the double-tree G,and pass through the fixed head I) of the box B, and on both sides (orthrough the center) of the spiral spring 0; also through the plate F,which constitutes the movable head of said box. Nuts (1 are screwed onthe ends of the clevis-legs a, to prevent detachment of the plate F. Theclosed end 6 of the clevis A is on the front side of the double-tree,and the single-tree H is attached thereto, as shown. When traction isapplied to the latter the plate Fwill be drawn into the box B,and thuscompress the springO more or less, according to the degree of pressureor tractive force.

To allow the requisite lateral movement of (No model.)

the clevis A and box B, the plate D is provided with lengthwise notchess, as shown in Fig. 3, and the box is pivoted at f to the plate E on therear side of the double-tree H.

The plate F has a circular groove to receive the end of the spring-coilC, so that thelattcr is held equidistant from the sides of the box.

By the arrangement of parts as described the clevis forms the chiefmeans for connecting the attachment with the double-tree and supportingit thereon; and,the tractive force being applied on the rear side of thedoubletree, we avoid the use of special devices for securing theattachment, which would be required if the attachment were applied onthe front side of the double-tree.

lVe propose to apply our improved device to the ends of a single-treealone, as well as to the ends of a double-tree.

We are aware of the application of a spring to a draft attachment of awhiffletree, and therefore restrict ourselves to the following:

1. The combination of the box B and plate E, pivoted together, as shownat f, and the spring 0, sliding plate F, and clevis A. which is attachedto the latter and extended, as shown, to adapt it for use,as and for thepurpose specified.

2. The combination, with the double-tree and notched plate D, securedthereto,ot' the clevis A, the plate E, and box B, pivoted together, asshown, the spring 0 and plate F, all as shown and described, whereby theclevis is adapted for lateral vibration, and such movement is limited,as specified.
